Custom Underwear for the Japanese and Korean Market in Rib Knit with DTF Film Printing for Japanese School Uniform Programmes

Custom Underwear for the Japanese and Korean Market — Rib Knit with DTF Film Printing

We supply underwear to japanese and korean buyers built for cold Korean winters. Cloth weight, weave openness and colour fastness are specified for the climate first: Rib Knit at 210-260 gsm, shade-matched to hold through the Korean back-to-school season. Programmes start at 200 pieces per style per colour and ship to Yokohama or Kobe.

The failures here are predictable: inconsistent sizing between production runs, and suppliers who disappear once the deposit is paid. We lock the specification before bulk — weight, shrinkage, stitch density and tolerance — and prepare the conformity documents for Japan so containers clear instead of accruing demurrage while the Korean back-to-school season passes.

Import, duty and delivery

Japanese Household Goods Quality Labelling compliance is arranged before the goods leave the factory. We ship to Yokohama or Kobe with the commercial invoice, packing list and certificate of origin. Buyers here inspect to a tighter standard: needle detection, dimensional stability after washing and seam appearance are checked before packing, and labelling follows the Household Goods Quality Labelling rules rather than a generic care tag.

FAQ

What file formats do you need for artwork?

Vector files (AI, EPS, PDF) give the best print and embroidery results. For raster artwork please supply at least 300 dpi at the final print size. We digitise embroidery files in-house and return a sew-out photo for approval.

How long does sampling take?

A first prototype is typically ready in 12 working days after the tech pack is confirmed, including fabric sourcing if the base cloth is not in our stock library. Revisions add about 3 days each.

Can you match a specific colour?

Yes. Send us a Pantone TCX reference or a physical swatch. We return lab dips for approval and hold bulk shade within the agreed tolerance band before cutting.

How is shipping handled?

We quote EXW, FOB, CIF and DDP. Consolidated sea freight is the default for bulk programmes, with air or express options when a launch date is at risk.
